简介:目的总结单绒毛膜单羊膜囊(monochorionicmonoamniotic,MCMA)双胎妊娠并发脐带缠绕的围产儿预后和产科处理经验。方法回顾北京大学第一医院2013~2014年收治的2例MCMA双胎妊娠并发脐带缠绕的病例,同时进行相关文献学习。结果2例MCMA双胎妊娠均在孕11~12周经超声确诊后保持密切随访。其中1例于37周择期剖宫产时发现脐带缠绕,另1例于孕21周发现脐带缠绕,孕29周因胎儿窘迫行剖宫产终止妊娠,母儿结局良好。结论目前大多数学者建议对MCMA双胎在妊娠32~34周择期行剖宫产终止妊娠,并于分娩前应用类固醇激素促胎肺成熟。但临床处理应在遵循该原则的基础上,重视胎心监护和超声的综合评价,针对具体病例制定个体化的治疗方案。
